Patented April 9, 1907.

To ii/Z lulu/n1, H1 may concern.-

Be it known that I, JAMIcs MQNAMARA, temporarily residing in the city of Montreal, Province of Que bec, Dominion of Can- 5 ads, have invented. a new and useful Iniprovernent in Matrices for i\lon.oline-l\lachines, of which the following is a specification.

l invention has reference to an im )roved n'iatrix, designed more particularly"or use in the 1nonolinc-machine or line-casting ma chine represented in application for Letters Patent of the United States filed by 'me on the 14th day of July, 1905, Serial No. 269,748.

in this class of niachines elongatcd matrices provided with suspending hooks at their upper ends are provided each in one vertical edge with a series of independently-usable characters and in the opposite edge with a. 20 corresponding series of notches to cooperate with alining devices, 'whereby the matrices in a composed line. are held temporarily in such relation to maintain exact alinement of the selected characters therein. -In the action of these machines the matrices are permitted to fall one after another into an assemblingbox, from which they are delivered laterally to the line, their descent being arrested at one side or another by underlying movable stop-plates in order to bring the selected character to the assembling-lc When the descending matrices strike upon the arresting or stopping devices, there a tendency to rebound, in conse quence of which they are liable to assume incorrect positions, so that proper action of the machine is prevented. 1n the ori inal machines this rebound was prevented y a s} 3ringpawl or dog, which acted against the matrices during their descent and engaged in their aiming-notches successively. In practice it was found that the detenting dog or pawl was nncert' in in ion and that it caused. a wear oi" t aiining notches suilicicnt to prevent the proper action oi. the alining devices, in. consequence of which the type c|1ara rters on the sings and in. the resuiting print were frequently out of line.

In my improved .n'iacl'iine described in the application above named I have provided a series of keepers or detcnts adapted to en gage the lower ends of the matrices, so that GtCllOlLG will be held down in place the instant it is arrested. The machine also includes distributin; mechanism containing a series of overlapping plates, from one end of which the matrices are suspended, the arrange ment being such that the matrices suspended from one plate will be overlapped by the next plate while they are being raised to the dis tributing-level. In order to meet the peculiar conditions of this machine, I construct my improved matrix with a suspending-- hook, with the matrix in one "edge and the dining-notches in the opposite edge in sub stantially' the same manner as heretofore; but I further provide them with a special notch near the lower end adapted to be engaged by one or another of the keepers.

1n the accompanying drawings, liigure 1 represents a side view of a matrix con-- structed in accordance with my invention;

'Fig. 2, a front edge view of the same; Fig. 8,

a rear edge view of the same. Fig. 4c is a side view illustrating the manner in which the lower end cooperates with the arresting de vice and the keeper.

Referring to the drawings, A represents a matrix consisting of a continuous fiat plate having parallel vertical edges and a suspending-hoo c at the upper end. One of the vertical edges contains a series of notches each with an intaglio character or matrix proper a therein. There are usually from ten to twelve of these characters; of similar width in each matrix The opposite edge of the mm trix is provided with a corresponding hum her of notches a designed to cooperate with the alining devices. So far as described the matrix resel-nbles those heretofore in use.

In constructing my improved matrix. I continue the body portion below the iowest character and form therein near the lower extremity a special notch c preferably in the edge which contains the matrices, to co operate with the series of keepers or no tents hereinafter described. The corner of the matrix below the notch a is rounded or bcvelcd, shown, in order that it may readily pass the engaging or detaining devices. in-

stead of forn'iing the book a with the rounded .top surfaces, as before, 1 form it with a flat surface on the top, as shown at a In Fig. 4, B B B B represent a series of horizontally-movehlo stops 01' plates used in the machine to arrest the'deseending matrioos at different heights, aecording t0 the olmmeter which is to he brought into use.

Q (.i {C C C are a series of horizontellymovable keepers or detents. The matrix desoends between the stops and The keepers and after being arrested by one 01' the fori'ner is instantly engaged by one of theletter, the stop being; moved under the matrix from one side, While the keeper moved into the notch o l'ro'n'i the opposite side.

Owing to the existence of the special notch. at the lower end of the matrix, I am enabled to zmtke use oi the series of keepers or detents to look the matrix down in each of the positions in' which it is arrested, and this without having the (lotentsor looking de-- ices ride over or against the upper edgos of the :-m1l; :'-i: omit-aiming the 'el'uiroeters and a ining-i'iotolies. Allrleviees here fore pro virleri inventing the rebound oi the matru :8 w compelled to ride against their edges, iii the result was a. mutilation of the ahns rig-stitches or of the type elm-meters.

i loving described .my invention, what I claim, and desire to secure by Letters Petout, is-

prising a body portion provided with a suspending-hoot; with the matrix characters in one edge, with the Mining-notches in the oppositeedge, and also with a special detaining notch a below the characters. 2. A monolineqnatrix comprisinge body portion with a. suspendingyhook at the top, a series of matrix el'ia-reotors in one edge, and a single detaining-notch in said edge below the (:l'litl'tLCtGIS. 3. A monfolilie-matrix comprising; a body portion having; in one mlg e n serio' of eh areaters, in the opposite edge u like number of Mining-notches, special detaining-notch a, i In testimonywhereofl hereunto set my hand, this 26th day of December, 1906, in the presence of two attesting Witnesses.
